Method Detail

*** This method is subject to change. ***

### setWhatToCompare

    public void setWhatToCompare(ExpressionInterface expr)

  Sets the expression for what the pattern is to be tested against (`<whatToCompare> [NOT] LIKE <pattern>`).

  Property change events signalled:

  - EVENT_WHAT_TO_COMPARE_CHANGED

  Parameters:
    `expr` - left side of conditional expression

*** This method is subject to change. ***

### getWhatToCompare

    public ExpressionInterface getWhatToCompare()

  Gets the expression being tested for the pattern

  Returns:
    the left side expression.

*** This method is subject to change. ***

### setPatternExpression

    public void setPatternExpression(ExpressionInterface expr)

  Sets the pattern expression portion of the LIKE expression.

  Property change events signalled:

  - EVENT_LIKE_PATTERN_CHANGED

  Parameters:
    `expr` - right side of conditional expression

*** This method is subject to change. ***

### getPatternExpression

    public ExpressionInterface getPatternExpression()

  Gets the pattern expression for this LIKE expression.

  Returns:
    the right side expression.

*** This method is subject to change. ***

### setEscapeCharacter

    public void setEscapeCharacter(java.lang.Character escape)

  Sets the escape character portion of the LIKE expression.

  Property change events signalled:

*** This method is subject to change. ***

### setMatchManyCharacter

    public void setMatchManyCharacter(java.lang.Character matchMany)

  Sets the match many character to use in the LIKE expression. If set to null, the default match many character of "%" will be used.

  Property change events signalled:

  - EVENT_MATCH_MANY_CHAR_CHANGED

  Parameters:
    `match` - many character to be used in the LIKE expression or `null` to reset to default

*** This method is subject to change. ***

### getMatchManyCharacter

    public java.lang.Character getMatchManyCharacter()

  Gets the user set 'match many' character used by LIKE expression or `null` if the user has not set one and "%" will be used.

  Returns:
    the match many character used. Otherwise `null`

*** This method is subject to change. ***

### setMatchOneCharacter

    public void setMatchOneCharacter(java.lang.Character matchOne)

  Sets the 'match one' character to use in the LIKE expression. If set to null, the default match many character of "_" will be used.
